Good morning fellow students. My name is David Loffert and this presentation covers the detrimental health effects of the toxic dust cloud that resulted from the collapse of the twin towers on September 11th , 2001. After a brief introduction to the physiology of the respiratory system, I will move on to present and discuss the detrimental health impact on people and the environment as a result of exposure to the toxic dust cloud.

Mr. Loffert:
Thanks for the excellent and very informative presentation. Your slides, accompanied by the audio narration were excellent. Your coverage of the issues, although complex, was well done. And, the pictures gave a sense of the magnitude of the catastrophe.

Thanks for taking the time and effort to create an outstanding presentation.

p.s.
The use of audio enhanced the presentation greatly. Taken a step further, one could also make the web addresses that you offered in several slides and in the resource list function as active links, allowing one to immediately be taken to the resource web site. Again, great job!
